Server has recently been updated to v1.3.1 - A full list of the minecraft patch notes can be found here.

General

Server difficulty has been raised to HARD to make the game more challenging:

Zombies are now capable of destroying wooden doors.

Zombie pigmen can now escape the Nether into the Overworld. The portal at Dragonstone is safely contained, however the one in The Vale is only partially contained. Use with caution.

You will now die of starvation instead of being reduced to 1 heart on normal difficulty

Catacombs

Has been updated from v2.0 to v2.5. This is mostly behind the scenes stuff, however the following changes are noteworthy:

All dungeons in the world have had their Wooden Doors upgraded to Iron Doors. This means that zombies will no longer go crazy bashing doors. Iron Doors inside a dungeon will still operate like Wooden Doors - simply right click to open and close.

If you die in a dungeon, you will now respawn in the hut above it instead of at the Spawn point, or your currently set bed.

Players can no longer hurt each other inside of dungeons - no more accidental friendly fire!

There is now a reset button above the end chest in a dungeon. Clicking this will teleport all players back to the entrance of the dungeon, and reset it for another attempt.

Traps (Dispensers) have been altered. Instead of a 100% chance to contain 10 arrows, they now potentially can do the following:

50% chance to contain 64 arrows

40% chance to contain 64 Fireballs

10% chance to contain 10 creepers

Chance for a room to contain a trap has been increased from 10% to 20%

Additional patch notes to follow soon. Was planning on getting everything done today, but there was a lot of catacombs work to do. Other plugin updates to follow in later patches!

SimpleSpleef's latest version apparently has lag causing issues with Minecraft 1.3.1, so not going to update it for now. You'll just have to ignore the message about updating it when you log in (if you can see it).

PermissionsBukkit is up to date.

Stargate has a minor update available, but not bothering with it for now.

Stargate DHD is up to date.

ThunderTower has been upgraded from 1.3.5 to 1.3.6 - No notable changes
